Description

A kind of novel quantitative liquid mixing bottle

Technical field

The utility model relates to the chemical analysis technical field, especially relates to a kind of novel quantitative liquid mixing bottle that can quantitatively reconcile reagent dosing ratio.

Background technology

Present domestic laboratory reagent dosing is still quantitatively extracted from reagent bottle with pipette and rubber pipette bulb mostly, and then is blown into the appearance agent in the pipette in the testing container with rubber pipette bulb, and this kind mode efficient is low; And be prone to produce error, influence experiment effect, external now for raising the efficiency, reduce experimental error; Just attempting making bottle end liquid dispenser and replacing the manual liquid dosing that moves with the principle of piston or air pump, but because such liquid dispenser complex structure, not easy care and correction; Price is high; Safeguard and the use cost height, improved efficient, shortened the time though do when testing; But the workload of later maintenance maintenance has increased, and these shortcomings have stoped external bottle end liquid dispenser applying in chemical engineering experiment.

Summary of the invention

The purpose of the utility model is to overcome the shortcoming that exists in the prior art; Provide a kind of simplification to move liquid dosing operation, alleviate laboratory work intensity, reduce operate miss, improve work quality; Can reduce a staff simultaneously contacts with the direct of medicament, can avoid medicament quantitative liquid mixing bottle leakage, safety and environmental protection that in the laboratory, volatilize simultaneously.This liquid mixing bottle not only has the quantitative accuracy of higher dosing, security, simplicity, and use cost and later maintenance cost of upkeep are lower.The technical scheme that adopts is: a kind of novel quantitative liquid mixing bottle; Comprise bottle and bottle handle, there are bottleneck and bottle cap in said bottle top, it is characterized in that: be communicated with drain pipe on the said bottle; Said drain pipe front end is connected with quantity tube; There is plug valve the end of said quantity tube, also has the liquid pressue device on the said novel quantitative liquid mixing bottle, and said liquid pressue device is connected with bottle.

The technical scheme of the utility model also has: said novel quantitative liquid mixing bottle also comprises the variable pipe, and the said variable seal of tube is connected between said drain pipe and the quantity tube.

The technical scheme of the utility model also has: be connected with screw thread between said quantity tube and variable pipe, the variable pipe, have O type ring to seal between the said screw thread.

The technical scheme of the utility model also has: said liquid pressue device comprises the unidirectional air outlet valve that is installed in the bottle upper end, is connected with bottle, and said unidirectional air outlet valve connects rubber balloon, also is provided with breather cheek valve on the said rubber balloon.

The technical scheme of the utility model also has: said rubber balloon is fixed on the said bottle handle.

The technical scheme of the utility model also has: on the said bottle observation window is arranged, the upper limit position of said observation window is concordant with the lower position of said drain pipe.

The technical scheme of the utility model also has: on the said drain pipe tiltedly, near an end diameter of said bottle greater than diameter away from bottle one end.

The technical scheme of the utility model also has: said bottle and bottle handle are injection molded by the plastics one.

The beneficial effect of the utility model is: 1) operation is very simple.Quantitatively only need hold the bottle handle during dosing, tilt liquid mixing bottle once, make reagent be full of quantity tube; Reset then, Unscrew plug valve is again held the hand-tight gas transmission balloon that is fixed on for twice on the handle of holding of bottle handle; Work has just been accomplished, and then the rotary closing plug valve gets final product.Because the quantity tube internal volume is fixed; The liquid that surpasses this volume can flow back in the bottle along the drain pipe lower edge, and quantity tube is full when needing only the inclination body, need not check that check and correction just can guarantee the accuracy of quantitative liquid getting; Thereby both reduced workload, avoided operate miss again.When needs dispose the reagent of various dose continuously; Basic identical with quantitative dosing; Only between drain pipe and quantity tube, add a segment variable pipe; Reach through continuous turn variable pipe outer tube and to change variable pipe internal capacity purpose at any time, volume and the addition of quantity tube volume after the variable pipe changes promptly are the volumes that will allot solution.Each becomes series to quantity tube by volume size with the variable pipe, can use quantity tube and variable pipe according to different user demand combinations.

2) safety and environmental protection.Because guaranteed only to give vent to anger on the rubber balloon structure that gas transmission is used on the one hand; Do not fall gas; Even and can make the bottle reversing also can leakage, adding has plug valve on the quantity tube, thus the sealing fully when having guaranteed that bottle is not got liquid; Avoided leaking the laboratory environment that causes and polluted, protected staff's health and safety because of the reagent volatilization.

3) simple in structure, directly perceived, be prone to working service, cost is low, is prone to promote.Complete equipment almost 80% above material is formed by plastic injection-moulded, and cost of manufacture is low, and design accuracy is controlled easily, and the accessory maintain and replace is easy, has guaranteed the low cost of later stage maintenance.

4) overcome the inner easily stifled data of state outer blank end liquid dispenser and be prone to drawbacks such as drift, strong to all kinds of medicament adaptability, the use highly versatile uses more bold and resolutely, and data are accurate.Medicament when to a certain degree being difficult for drawing, generally needs dosing again less in reagent bottle, and is accurate to guarantee measurement data; No matter be the pipette dosing of domestic use, still external bottle end liquid dispenser dosing is because structural reason at present; Residual pharmacy can only be outwelled relatively waste on the one hand, more precious medicament; Increase environmental pollution on the other hand, and used this quantitative liquid mixing bottle that the residual pharmacy of being outwelled is minimized, farthest practiced thrift residual pharmacy; Both practice thrift fund, put and ended to waste, protected environment again.
